How Does an Air Conditioner Work?

July 18, 2016

The weather is reaching record numbers throughout the U.S. and the majority of homes are utilizing some variety of air conditioner to combat the seasonal heat. Though we are all thankful that your air conditioner is functioning, the experts at E.B. Air, LLC in East Bernard wants to give you a glimpse at just how an AC system works.

The Basics

There’s a plethora of science involved in keeping your house cooler. Your air conditioner functions in a similar way to your refrigerator, however your air conditioner has a bigger responsibility to manage. Both your fridge and AC cool with a reoccurring loop of refrigerant, with your AC this refrigerant loops from inside to the outdoors. This refrigerant effortlessly alters from a liquid to gas and back to a liquid again. It flows into your residence as a sub-cooled liquid and as it evaporates it soaks in heat from the indoors and turns back into vapor. This vapor then moves back to the unit outside where the heat is freed and is then condensed back into a sub-cooled liquid.

Four Components

There are 4 central sections to your air conditioner unit: a compressor, an evaporator coil, the condensing coil and an expansion valve.

The evaporator coil is the location your refrigerant evaporates from a sub-cooled liquid into a super-heated vapor. This component can be established in the home, in your garage or even in your attic. Warm air transports across the cold evaporator coil and the heat is taken from the air. This cooled air is then released throughout the space inside your home.

Your compressor sits in your outdoor condensing unit. The super-heated vapor from your evaporator coil enters into the compressor which increases the pressure of the vapor until it is changed into hot, high pressure vapor. The hot vapor then enters back into the condenser coil where less hot outdoor air runs across the coil, heat is moved outdoors and the refrigerant is adapted back into a sub-cooled liquid. The sub-cooled liquid returns to the indoor evaporator coil by an expansion valve or metering device. This continues repeatedly throughout the process.

That completes your physics lesson for now…your air conditioner runs on an never-ending loop of science. We understand that it’s not as crucial to you how it works, but just the fact it’s running.
